Ill have to find it, let me see what I still have.

Same for the components. It was basically just some relays and some opto couplers from memory.

I never deployed it in the end, mainly as the machine I was trying to retrofit the turret on (Harrison M300) struggled to move the weight of the turret, so I abandoned the idea.

I was using Centroid Acorn and then let the Arduino do the 'change logic'.
